To all whom t may concern:

Be it known that l, THOMAS CHARLES WIL- Lis PULLiNcnR, a subject of the King of England, residing near Dumfries, Scotland, Great Britain, have invented certain new and useful Improvements in the Construction of Water-Jacketed Engine-Cylinders, of which the following is a specification.

This invention is for improvements in or relating to the construction of waterjacketed engine-cylinders, and has for its object to provide a light construction of water-jacketed engine, the invention having particular reference to the method of making the joint between the jacket and the part carrying the same.

According to this invention, the enginecylinder has rigid with it an outwardlyprojecting shoulder at one end whichshoulder faces toward the other end of the cylinder, and the water-jacket has a corresponding internal shoulder at that end and a por-- tion which extends beyond the said shoulder to engage the side face of the shouldered portion on the engine-cylinder in order that it may be secured to the cylinder-portion by such extension, for the purpose of holding the jacket in endwise against the endthrust of packing placed between the two shoulders.

Preferably the end of the jacket not secured as described above, is provided with a gland for packingwhich bears against a circular portion rigid'with the engine-cylinder.

In the accompanying drawings which illustrate one method of carrying out this invention Figure 1 is an elevation in part section of a cylinder-block with jacket attached;

Fig. 2 is a vertical section through the block of cylinders at right-angles to the section shown in Fig. 1 and centrally with one of the cylinders, and

Fig. 3 is a plan of the gland-plate for closing the lower end of the jacket.

Like reference letters indicate like parts throughout the drawings.`

The block of cylinders shown in the drawing comprises the usual head A .into which are secured by any convenient means cylinders A1 which may be of for ed steel. rll`he head projects laterally eyond the cylinders at A2 and in this project- Specication of Letters Patent.

Application led April 4:, 1913. Serial No. 226,735.

ing portion a continuous shoulder A3 is provided which extends around the whole head and faces in the direction of the endsv of the cylinders remote from the head.

A sheet-metal water-jacket B conveniently of steel is provided with a shoulder B1 corresponding tothe shoulder A3 on the cylinder-head and beyond this shoulder is an extension B2 which is shaped to tit around the projecting portion A2 of the head which, as indicated, extends around the entire block.

Between the shoulders A3 and B1 a rubber packingring C is placed and in assembling the parts, the water-j acket is thrust endwise against this packing so that the packing is 'compressed and when so compressed the jacket is secured to the head by screws ,B3 which extend through the portion B2 of the jacket and engage the part A2 of the head. A water-tight joint is thus provided by the packing C between this`end of the water-jacket and the head of the cylinder-block.

rThe other end of the water-j acket is closed by a plate D shaped to fit the jacket and which may be secured thereto by welding. 1n this plate holesD1 are provided one for each cylinder,sothat the cylinders project therethrough and that portion of each cyllnder-wallv which lies opposite the plate D is thickened as at D2, say, by securing a piece of metal around it, for example by welding a band thereon, and this thickened portion has its outer face turned true. The wall of each hole 4D1 is recessed and screwthreaded as at Da to receive. a ring-nut D4.

ln assemblingv the parts-a rubber packingring D5 is placed in each recess provided in theV wall .of each hole D1. A compressionring D is then inserted and the ring-nut l)4 screwed home so that the packing-ring is forced inward against the wall of the cylinder thereby forming a watertight joint between the cylinders and this end of the water-jacket; the it'aces oit the parts bearing against the packing--rinjj` are sloped to drive the ring inward.

What li claim as m. invention and desire to secure by Letters atent is z- 'llhe combination with a vcylinder-block wherein the head end is rovided with a continuous outwardly-projecting shoulder which faces toward the other end ot the cylinders, of a water-jacket surrounding all the aiol cylinders, having a corresponding internal shoulder at the head end, a portion which extends beyond the said internal shoulder to engage the side face of the shouldered ortion on the cylinder-block, the bottom o the water-jacket being filled in with a plate provvided with holes to permit the extension through it of the cylinders and glands secured in the plate and engaging circular exterior faces which are circumferential to the 1C cylinders, substantially as set forth.

In testimony whereof l alx my signature.

THOMAS CHARLES WILLIS vPULLINGER.
